As the gallery shows, the two cars do look a lot alike, though there are notable differences--and they're not all related to the Competizione's racing lifestyle.

The original, road-going P4/5 by Pininfarina is based on a Ferrari Enzo, rebodied at the cost of about $4 million by Glickenhaus to echo the look of Ferrari's 1960s race cars. The P4/5 Competizione is based on a much less exotic F430 chassis.

Regardless, these are two beautiful cars, and seeing them together is like seeing a distant but entangled quantum pair united at long last.
